Small artwork series for a charity

I'm looking for a small series of illustrations to represent non-profit charities. This is for artwork as part of GlobalChange.io

The nonprofits are as follows:

New Story Charity
The hunger project
free software foundation
Watsi
songs of love
rainforest foundation

I'm looking for 2-3 small illustrations for each, so up to 20 pieces of artwork.

I'm paying for this out of pocket, not other funding, so I'm trying to pay small amounts. But hopefully your artwork will be featured on GlobalChange currency!
